Patented Dec. 5, tlx'? Application filed January 21, 1916. Serial No. 713,376.

T o all whom it may concern 3e 1t known that l, AUGUST. Hoinz, a citizen` of Germany, residing at GrantPark,

in the county of Kankakee and Stateof Illi-L.;

nois, United States of America, have invented certain new and useful lImprovements in Locking-Closures for Containers,

I- of which the f ollowing is a specification.,

The present invention relatesI to containers fand the like, and more particularly to new aid useful improvements in locking closures therefor.

An object of this invention is to provide an improved removable closure for a receptacle which is capa-ble of securement on the receptacle rendering the same air tight.

Another object of this invention is to con-` struct a closure foncontainers, which` when secured in position is 'air tight and non-rat tling, and wherein the usual bail is modified to -form means for clamping the closure in position and engageable by a suitable lock-` ing element. l

A further object ofthis invention is to ,provide clamping means Vfor 'forcing the closure into position on thecontainer, Aandr also to provide means for locking 'theolo- Other objects and advantages will appear from the following detail'description andv the claims, taken with' an' inspection of the accompanying drawing-in which-1 Figure ll is a fragmentary side elevational view of the containery showing a closure thereon embodying the 'improvements of my invention, Fig. 2V is a. transverse vertical sectional view taken on line 2-2 of Fig.r land looking im the direction of the arrows, Fig.

3 is a similar view taken on the line 3-3 of' Fig. 2 looking in the direction of the arrows, and Fig. 4 is a top plan view of my inproved closure. f

Referring more particularly tothe drawing, `wherein similr characters of reference designate like and corresponding parts throughout the various viewsfl designates a container body o the shape. usually employed in' milk can'sand thev like, having 'a neck 2 formed on the upper end thereof, said neck ,having the free marginal e'dgethereof bent outwardly to form an annular flange 3. The flange 3. is annularly` depressedtotprovide a recess 4 fr" reception of a sealingrk washer 5 of rubber or the like.

The closure designated 6 in its entirety, comprises a body portion formed of a cirthe strip maybe offset, or

.cular Sheet substantially concave-convex i.;

crosssection and provided with a periplol ,.-eial flange 8. A collar portion .9 having an on its outer -margina annular flange 10 edge is carried by the sheet 7, thefianges and 10 being coincidental and the faces thereof soldered or'otherwise connected. Si

`handle 11 is mounted on the 4closure to facilitate its removal at times. The collar l? is receivable in the neck 2, in the same inanner as the usual milk can covers are inserted,

the flange 10 bearing upon the washer 5 and therebyrendering air tight the joint. A strip 12 is arranged diametrieally on..

the closure, the opposite extremities of said I provide meansfor clamping the closure :.3

in position. For this purpose a lugs 17 are carried by the neck.A vided with apertures 18 in lwhich my'iinproved clamp hereinafter described, is journaled. The lugs are oliset as at 19 to lie free Aof theilanges .3, \\8, and 10, a plurality of 'tonguesl I20 being ,formed lon' the lugs and bent' upwardly 21 for reception of the arms 13.l

My Iimproved clamping means comprises plurality of a bail 22 formed-of a strand of wire'bent on' its extremities tov provide cam portions '2,3 and journalportions24. A hasp 25"is`car ried' by the bail preferably at .the intermediate portion thereof i*and may be engaged over. a loop 26 through which may be 2 and proy to form a pair of seats arranged padlock 27.`of.any desired type.

In use my improved closure is plaoed'on the container,the collar 9` being introduced into the neck 2. The closure is now turned until. the arms 13 engage in the sea'ts21. The bail when unlocked is in an upright or vertical position, the earn portions 23 being remote from the arms 1,3. However, when the arms are in their seatsthebail is, moved to the position shown in the drawing Where` upon the` cam portions will engage the arms sa' 1,2ow44 firmly clamping I the closure in position Twisting of the closure is rendered impossible b v the Seats Q1 thereby rendering it practically impossible for the closure to become accidentalliY dislodged. T he operation described in the foregoing is reversed or removing the closure.

It will be readily apparent that the bail may be formed of material other than wire, and that the' lugs 1T ma)Y be integrally formed with the neck departing from the spirit and scope of my invention. It will be understood. ot course. that the use ofthe present invention is not limited to milk cans, but is capable of appli cation to various types and structures' of containers with slight modification.

From the above description taken in connection with the accoinpanyingr drawings, it is thought that a clear and comprehensive understanding of the construction,

to secure b v Letters latent is:

l. The combination with a container having a neck extending therefron'i. of a closure having marginally arranged projecting arin.-. said neck having a bail thereon and, receiving recesses for said arms, said bail having cam portions for engagement `with the arms to maintain the closuic on the container. A
